Well hopefully it would fix it.

You know that’s a pattern I already observed, on reddit, on /r/cyberpunk. People were posting pictures of cyberpunk cityscape, and scene, and character, both male and female, then more female character, then less and less dressed, until it became the majority of the content. Several users enjoyed it, a lot did not. In the end the discussion resulted in the creation of /r/cyberbooty and everyone was happy.

You’re allowed to post whatever you like, and so am I. What I am I asking you to do, is think more deeply about what you should post.

I feel that this advice of yours is extremely similar (and not more offensive) than what I posted in my first comment. I did think and still think that this image (which is not the first offender) was counter-productive and I tried to give elements to explain why I think it should not have been posted there.

Happy to see we both agree that it is fair to point out when someone posts things we don’t like.

We really didn’t need to trade words for you to figure this out.

Yes, still a bit surprised you opted to.

Why do you post images here then?

This is not danbooru, this is a discussion board. You don’t want any discussion? We are only allowed to post praises?

But sometimes, an opinion isn’t worth sharing.

Likewise for images.

If the only person who likes hearing about a thought you’re having, is you, then it doesn’t need to leave your head.

You were not the target audience. The community at large was. And it was a failure because no one really chime in in support, but I had no way of knowing before posting.

You are worried over people expressing their opinion on a platform designed for it?

What is the comment section about, in your opinion?

Well yeah, I think I was clear that I disagree with your opinion. Of course I am dismissing it, especially with you giving no other argument than saying it is rude to state my opinion. Disagreeing I do all the time with other people without assuming they have mental issues. We have different tastes in art. What is more natural than that?

The concern is genuine. You are getting abnormally défensive, angry and paranoid about a post on an image board. Why do you care that much?

I am saying that lovingly and without sarcasm: you are very clearly overreacting. Maybe show that conversation with people you trust and like and get their opinion but you are having an abnormal tantrum.

Are you having a bad time in life?

Sorry for not liking the content you post on a platform designed to comment on posts.

You asked for specifics, I gave them.

I post when I find content I like.

Is it your art? If not do you realize how overreacting you are?

I find it more polite to explain the downvotes than just downvoting. And communities require discussion and disagreement. No one upvoted my opinion, I guess you were the one to downvote it, so there is no way to know who is more aligned with the majority. This is indeed the type of content I feel does not steer the group in the good direction and I will probably leave if it dominates.

Of course it is subjective, and saying that picture convey no atmosphere is just me being polite. The pose, the clothing, the lack of action, actually gives it an atmosphere: a pin-up/waifu atmosphere. This is not really what I am looking for here.

We disagree, I explain why. I don’t think I am being insensitive, my opinion is as valid as yours, I explain it. You are free to disagree. I don’t see where assholishness comes into play.

If you are insulted by factual statements, take a deep breath and look within.

This image literally does not contain anything beside a character, doing nothing in particular. It has no background, no action, no atmosphere.

Maybe I am the only one in that case but just wanted to say: I subscribed to this because it was filled with chill images that helped project in imaginary places. I hope this does not become a WitchWaifu board.

If the point of the image is just to show a sexy girly, maybe this is not the most interesting place to post it in?

The fact that you assume I don’t understand that obvious fact clears that out that this is not a serious discussion. You think “plane, heavy, need fuel” “blimps cool, lighter than air” and work your calculations from there. I am sad I wasted so much time in it.

Ok so scaling blimps up is realistic but planes not, no justification needed. I see, ok, bye.

10-20 American football fields in size.

So about 20 times the biggest wing area that we currently have? Is this what you are scolding at? Is this your physical impossibility?

What’s the obsession with blimps by the way? If you are afraid by enormous sizes please tell me you have done the calculations there…

Let’s be clear, without joking I think you are wrong to dismiss these possibilities and that you have an almost pathological lack of imagination. Yes, science fiction is about techs that do not exist yet are plausible.

You can fit a pool and a greenhouse in 250t. 40 cubic meters of water is 40 tons, 40 cubic meters of soil is basically the same. You have room to spare for the tennis court.

I am not a pro aviator, but I am a pro engineer, on an unrelated field, but I can do my napkins calculations. I mentioned the An-225 to make a point on the physically possible payloads that are possible today, with proven tech. I am not proposing we need those neither do we need the exceptional specs of that exceptional plane.

We scale down speed, it scales down drag (and necessary thrust) quadratically. We assume better efficiency on solar panels, batteries and motors because that’s what we will have in the future. Needing thrust only for sustaining flight and not for take off is another x5 factor on your calculation.

you’d still need at least 40 000 - 150 000 m2

Look at you! You managed to scale down your initial super confident 600 000 m² estimate by an order of magnitude! I am proud of you!

but as a wild guesstimate, I’d say the an255 needs some 40 000 to 120 000 kW for sustained flight in fair weather.

From what I am reading this is about the amount of power an airliner uses at max power on all the engines. You are looking at 1/10th to 1/20th of that for sustained flight, and quadratically less at lower speeds that those typical of those airliners.

We do have helicopters. We have canadairs, we have hovering drones.

You are arguing about a technicality that has been worked around.

Dammit, here I am, arguing over the feasibility of a fantasy, between a hamster in warhammer gear and a knitted armor. sigh

Dude chill, I merely mentioned the An-255 because you sounded like you were arguing that flying a pool and a greenhouse was somehow breaking a law of physics. It does not, you can fly both for the 250t (that’s payload only btw, that does not count fuel(+300t!), engine, structure) that this plane can lift.

I am not proposing to develop the same amount of thrust, speed, dry range that it exhibits, these are different beasts. Actually, in my fiction, these “sky palaces” only have the thrust needed for sustained flight, and can’t lift off unaided.

Now don’t get me wrong I’m no nuclear shill,

I am, but I am also an avid dreamer of new tech.

The record for efficiency for solar panels in a laboratory setting is 47%. Those aren’t commercially available. Commercially available ones are currently around 22%.

Sci-fi setting, honey. If 47% is achieved in the lab that’s the bare minimum of what is credible for future tech.

I am happy you made the calculation for something that can drag 300t of batteries at half the speed of sound and can produce the constant thrust the An-225 needs for take-off but that was never the proposition. I am proposing a slow vehicles, with a fairly big lift due to its large wings so probably able to fly at a much lower speed, generating far less drag, drag being the main lower bound for the thrust needs. Probably going at speeds where propellers are much more efficient than jet engines. All of this adds up to levels I don’t care to calculate because this is a fantasy.

However yes, that’s a proposition that still requires extremely large wingspans. And yes, putting a swimming pool in an airplane is kind of a ridiculous proposition, but it is kind of the point I want to make: nowadays that would be a very wasteful ridiculous thing to do. With this sort of tech? It does not harm anything or anyone. It does not burn fuel, it does not emit CO2.

All I know for sure is that eternal planes are a thing that is possible right now, and that better tech will allow us to make them bigger.

Yes and? You do know that current cargo planes are able to lift 250 tons without violating the laws of physics?

Just to be clear “eternal planes” exist today. They use solar during the day, batteries during the night. Unmanned they last forever and a 2-person plane like this already exists now.

What I am proposing is science fiction, but honestly the most straightforward and boring kind: I am proposing that from this current state, we will continue, percent by percent, improve efficiencies in batteries, motors, solar panels, we will improve material resistance and aeronautic designs.
